To all whom it may concern.-

Be it known that I, Ross l/VALTER ToMLIN, a citizen of the United States, residing at Sheridan, in the county of Lasalle and State of Illinois, have invented a new and useful Combined Dump and Elevator, of which the following is a specification.

This invention relates to grain dumps and elevators, and has for its object to simplify and improve the construction of this class of devices.

l/Vith these and other ends in view the invention consists in a grain-dump having combined therewith a motor adapted to be operated by the horses attached to the wagon the contents of which are being dumped, the said motor serving also to operate the elevating mechanism.

The invention further consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural detailstherein exhibited, but that changes and modifications are permissible when such changes and modifications come within the scope of the invention and may be resorted to without departing from the spirit or sacrificing the efficiency of the same.

In said drawings, Figure 1 is a top plan "iew of a combined grain dump and elevator constructed in accordance with the principles of the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse sectional view taken on the line 3 3 in Fig. 1.

Corresponding parts in the several figures are indicated by like characters of reference.

The frame of this improved device includes a pair of longitudinal sills 1 1, which support a pivoted tilting platform 2, the pivots of which 3 3 are journaled in boxes 4 about midway of the length of the platform, which will thus be almost evenly balanced. At one end of said platform is provided an inclined approach 5, over which a wagon may be readily driven onto said platform. At the opposite end of the latter is a tread-power 6, consisting of an endless slatted apron moving over rollers upon a pair of shafts 7 and 8. An inclined passage 9 leads from the ppppr end of the tread-power to the groundeve . A longitudinal shaft 10, supported about parallel to the tilting platform, is provided at its front end with a bevelpinion 11, meshing with a bevel-gear 12 upon the motorshaft 7. A governor 13 is provided whichis likewise driven by the bevel-gear 12 and which serves to check the motor-shaft 7 when the latter revolves at a greater rate of speed than may be considered desirable. Y

14 designates a suitably-supported trans verse shaft, which is provided with spurwheels 15, meshing with racks 16 upon the under side of the tilting platform. The shaft 14 has a worm-gear 17 journaled loosely there on, but capable of being locked upon said shaft by means of a clutch 18, operated by a hand-lever 19. The worm-gear 17 is in mesh with a worm 20 upon the shaft 10.

21 is a brake-lever which is connected, by means of a rod 22, with a brake mechanism 23, whereby the power-shaft 7 may at will be held securely against rotation.

A bracket 24 upon one of the side sills supports a pivoted trough 25, containing an endless carrier 26, one end of which is mounted upon a roller on a shaft 27, having a sprocketwheel 28, which is connected, by means of a chain 29, with a sprocket-wheel 30 upon the shaft 10. The latter extends through the lower end of an elevator-easing 31, which is disposed below the discharge end. of the carrier in the trough 25, said shaft being provided with a roller supporting the lower end of the endless carrier of the elevator which is thereby driven.

Suitably connected with the side sills 1 1 are a pair of links 33, terminating in eyes 341, capable of being adjusted upon the rear hubs of a wagon to keep the latter in position upon the tilting platform when the machine is in operation.

In operation a loaded wagon may be driven over the inclined approach 5 onto the tilting platform, which latter is initially in approximately horizontal position, the horses being driven onto the tread-power, which is initially locked by means of the brake 23. When the horses are in position upon the tread-power, the brake-lever 21 is manipulated to release the shaft 7, whereby motion is communicated to the longitudinal shaft 10. The trough 25,

which while the wagon was being driven onto the t1lt1ng platform was 111 an elevated position, (indicated .in dotted lines in Fig. 3,) is restored to the position shown in Fig. 1, so that when the end-gate of the wagon is opened the contents of the wagon will pass into said trough, from which it is conveyed by the endless carrier 25 to the elevator, said carrier and elevator being driven by the shaft 10, as will be readily understood. At the same time the worm 20, meshing with the worm-gear 17, which latter is locked upon the shaft 14 by the clutch 18, serves to rotate said shaft 14, the spur-Wheels 15 upon which engage the racks 16, connected with the platform which is thereby tilted, so as to cause its entire contents to be delivered into the carrier-trough. When the wagon is empty, the brake-lever 21 is manipulated to apply the brake and the clutch 18 is disengaged from the Worm-gear 17, thus enabling the restoration of the tilting platform to its initial position to take place while the wagon is driven off the device to make room for another one.

Having thus described the invention, what is claimed is- 1. In a device of the class described, an evenly-balanced tilting platform, racks depending from said platform, a transverse shaft having spur-wheels meshing with said racks, a worm-driven gear loose upon said shaft, and a clutch to lock the worm-gear in position upon said shaft.

2. In a device of the class described, a frame, a tilting platform evenly balanced upon said. frame, and links connected with the latter and terminating in hub-engaging e es.

3. In a device of the class described, a frame, an evenly-balanced tilting platform, an inclined approach from the ground-level to said platform, a tread-power at the opposite end of said platform, a longitudinal shaft supported adjacent to and approximately parallel to the platform, connectinggearing between said shaft and a driven shaft of the tread-power, a Worm upon the longitudinal shaft, a shaft supported transversely below the tilting platform and having a gear meshing with said worm, a clutch to lock the worm-gear in position upon the shaft, pinions upon the latter, and raclvsegments depending from the tilting platform and meshing with said pinions.

In testimony that I. claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
